What Does Waterproof IP67 Mean?

What Does Waterproof IP67 Mean

When browsing through different headlights for your vehicle and checking their details, you are likely to come across the term IP67 or something like that. But what that means, you probably wonder. For starters, it is not hard to understand that the word actually indicates the waterproof level.

But still, many questions remain, including how it works, how much is IP67, or and what does IP67 mean. You won’t need to perturb about that anymore since we will discuss the matter in-depth on here. For any vehicle lover, any additional information regarding your vehicle parts can be vital. So, we also included details related to our main topic to assist you further.

What Is the IP rating?

First thing’s first, IP does not only indicate the waterproof level of any headlight. It can represent the resistance to dust, sand, or any such solid object too. Meanwhile, it also isn’t limited to just headlights. You can find IP ratings on other products, such as smartphones, connectors, cables, adapters, etc.

IP is actually the short form of International Protection or Ingress Protection. If we put the definition in simple words, the IP rating is a unit that represents a certain object’s resistance to substances that are liquid or solid. The number after IP is what determines it.

How to Understand an IP Rating?

To understand any certain IP rating better, you should look at the two digits after it. The first digit between them is the determiner of its resistance to solid messes, such as sand or dust. It can range from 0 to 6. Meanwhile, the second digit is for liquid resistance that can be between 0 to 8.

If the first digit is 0, that means the headlight has no protection against dust. Having a 0 as the second digit indicates that it is not liquid-proof to any extent.

The Meaning of Different Numbers as the First Digit of IP

As mentioned, the first digit is for different levels of dust protection. You should know of each of these points we mentioned below when buying any headlight for your vehicle.

1. There is no protection from any solid object.

2. The headlight can resist solid things over 50mm, which can be any minor accidental touch by your hand.

3. It can resist up solid objects with more than 12mm. For example, your fingers.

4. Can tackle solid things like wires and any item that have over 2.5mm?

5. There will be protection from solid objects of at least 1mm. It can be wires with a thinner body.

6. Can survive dust, but not if too much of it enters the headlight.

7. The headlight is completely resistant to dust.

As you can understand, the higher this digit goes, the thinner a solid object your headlights can resist. Since we are talking about IP67, a headlight with that rating won’t face any issue against dust or such messes on the street. It is actually mandatory for headlights to have 6-level of dustproof because they can go faulty quickly otherwise.

The Meaning of Different Numbers as the Second Digit of IP

Meanwhile, the second digit of an IP rating is for the liquid resistance of any headlight. As it goes from 0 to 8, it kind of increases the protection from much severe pouring or jet of water. Without further ado, see the points below yourself.

  1. It indicates zero protection against liquid.
  2. The object with this level of liquid proofing can tackle water drops falling from a vertical angle.
  3. It can survive water sprays from up to a 15° vertical angle.
  4. It is like above. However, its vertical protection angle is up to 60°.
  5. It can stay okay while being sprayed from every direction. Many low-waterproof smartphones have 2, 3, or 4 levels of IP liquid-proof rating. But you should note that the object won’t handle it if too much liquid enters into it.
  6. It is almost like the above one. But instead of spraying, the item can resist up to low-pressure jets. The ingress is still limited and waters much than that can damage the object.
  7. It can survive high pressured water jets. Most of the time, items that need to stay on ship decks have this level of liquid-proof.
  8. The headlight can resist against immersion for 30 minutes with a pressure of 15cm to 1m. You should avoid driving too long during rain with this level of IP.
  9. Your headlight will survive heavy immersion for a long time, even under pressure. If you want to drive under the rain for a long time, this is a perfect rating.

We should mention here that having a higher IP waterproof level doesn’t always mean that it can tackle conditions for the lower levels. For example, if your headlight’s waterproofing is level 7 or above, that doesn’t mean that it can resist water jets like level 5 or 6. You won’t really find headlights with a waterproof level under 7 since they won’t survive immersions.

Apparently, almost all the headlights and other such items are available with an IP level of 67. You will rarely find IP68 on a headlight. Since a headlight needs to constantly go through dust, sand, moisture, and often rain, the only two ratings you will find in a headlight IP is 67 and 68.

Frequently Asked Questions

Is IP67 waterproof good?

This depends on the manufacturer of your car. Most car manufacturers offer optional waterproof headlamps, which you should get if you’re using your car in the rain or during heavy storms. These waterproof headlamps usually have better performance and can give your car a cleaner look.

What is the difference between IP66 and IP67?

IP66 is a rating that describes the ability of a product to resist dust, water, and dirt. It indicates that the product is able to withstand dust and water spray, but cannot protect against liquid splashes.

IP67 is a rating that describes the ability of a product to resist dust, water, and dirt. It indicates that the product is able to withstand dust and water spray, and resist against splash of water.

What's better IP67 or IP68?

IP67 and IP68 are both waterproof ratings for electronic devices. IP68 means that the device is water resistant and can withstand a short-term exposure to 1 meter of water, while IP67 means that the device can withstand short-term exposure to 1 meter of water. There’s no clear winner between the two.

However, you can use the IP rating of your device to decide which one to choose. If it’s not important, then go with the more common IP67 rating. On the other hand, if you need to protect your device against water exposure, then go for IP68.

Final Note

If we take all the above conditions into factor, we can generalize the term IP67 with ease. It basically means that a headlight has total protection against dust off the road and can stay okay under immersion of 15cm to 1m for a temporary period.

The IP level is vital for a headlight as, without enough resistance, it can get hazy, cloudy, and faulty pretty quickly. While a dirty headlight is inevitable, a high IP rating can reduce the risk and extent of it. So, make sure to check this rating when buying a headlight. Unfortunately, if you want to drive in the rain for a long time, you will find it hard to find a capable headlight.
